L531 "The object of. my invention is to provide a novel, eflective and inexpensive anti-skid device for vehicl tires, which device may be readily attache'd directly to and detached :irom the tire, thereby eliminating the necessity of providing 12 Claims. (oi-15 21425) flat bar from'which-the anti-skid device shown in Figs. 1,'-2 en less formed;

additional elements for securing the anti-skid I device'in position. c

Myinvention comprises broadly an anti slrid device for removable attachment directly ,to a vehicletire in any desired position around the tire, said anti-skid device comprising an-intermediate elastic portion stretchable across "the tread'ofthe tire and provided with means ior engagingthe tire on opposite sides of its tread.

My invention also comprises a resilient bar of the desired shape in cross section, said barbeingideveloped into a looped portion, to be stretched across the tire tread, the looped portionhaving inclined end portions terminating in inwardly directed ends arranged ingposition to engage the re on ,oppositesids .oiyt e t e trea he; sa ends being preferably. providedwithteeth adapted' to bite into the tire to prevent'the unintentionalcreeping or removal of the anti-skiddevice.

J My invention also contemplates the widening of the ends toprovide extended elementsior engagement of the tire.

In Fig. 14 I have shown as examples a round bar l5, a triangular bar I6 and a square bar II. It will also be observed that the inwardly turned ends of the inclined end portions 3 may be widened'to provide more extended engagements with the tire upon opposite sides of the tire tread. One of these widened ends is shown in Fig. 7.

In Figs. 15 and 16 the intermediate portion I8 is shown as an elastic solid material, as rubber, provided with inclined resilient end portions [9 permanently united therewith and having inwardly turned ends 20 for removably engaging thetire onopposite sides of its tread.
